Publicist Carrie Gordon said the decision is due to the stresses in Moore's life, and she looks forward to getting well.

In the meantime, Moore has dropped out of "Lovelace," the Linda Lovelace biopic in which she was cast to portray Ms. Magazine founder Gloria Steinem.

Gordon did not release any other details about the nature or location of Moore's treatment.

TMZ had reported Tuesday that late Monday night, paramedica responded to a 911 call at Moore's home and rushed her to the hospital after treating her for 30 minutes. The Los Angeles City Fire Department's spokesman confirmed that it had responded to the call, which he said was for an "unknown illness."

The past few months have been rocky for Moore. She released a statement in November announcing she had decided to end her marriage to Ashton Kutcher following news of alleged infidelity. The two were known to publicly share their affection for one another via Twitter.

The "Ghost" star still has a Twitter account under the name mrskutcher but has not posted any messages since Jan. 7.
